It's been a long time coming, and I'll bet most people thought it was already dead.
Star Wars Galaxies, the ill-thought out MMO collaboration between LucasArts and Sony, finally comes to an end on December 15th, 2011. Mourn it do not, miss it do not. This is actually the first Sony Online MMO to close, as even Everquest is still going. The main reason appears to be that their licence to use Star Wars expires in 2012 and they didn't feel it was worth renewing. A smart choice in my opinion, especially with The Old Republic around the corner.
Oh well, there's always Clone Wars Adventures right? Right?
